Auschwitz concentration camp

Who hasn’t read or hear about Auschwitz? It was a net of concentration and extermination camps operated by the Nazis during the II World War. It was the largest concentration camp and now it’s become a museum.
When Spielberg was filming his masterpiece Schindler’s List, he wanted everything to be as realistic as possible so, with a few arrangements by the production crew, he used Auschwitz camp as a filming location.
